v Our invention has for its object an apparatus, simple in construction, and complete in its operation, to be attached to packages containing butter, by the use of which access may be had to their contents, and a knowledge of its quality be obtained without the trouble and delayconsequent upon a removal of the heads thereof.

A hole should be bored through thehead of the frkn, tub, or other package, in .which the butter-is contained, of a size corresponding with the circular projection on the plate, which should be large enough to freely,r admit the trier.l Theplate should be adjusted so that the projection shall fill or close the hole, having beneath it a piece of thin gutta pecha, ory other suitable material for packing it,pa.nd being held in place by u screw through each end, thereby making it air and water-tight. i
